Obstructive sleep apnoea and type 2 diabetes: Whose disease is it anyway?

The association between type 2 diabetes mellitus (T2DM) and obstructive sleep apnoea (OSA) is increasingly recognised. Both conditions are rising in prevalence due to the increased prevalence in obesity, which plays a key role in both disorders. Emerging evidence suggests that T2DM and OSA may also be related independently of obesity. This raises the possibility that identifying and treating OSA in patients with diabetes could have an important impact on diabetes control and cardiovascular health. This article is a summary of the implications of OSA for patients with T2DM.
